A fuel cell is where the jailer keeps gas guzzlers. Scholars review chemical reactions, chemical bonds, and chemical structure in order to apply these concepts. Participants construct fuel cell kits, using electrolysis to run the car and...

Everyone enjoys combining baking soda and water. Here is a lesson that challenges scholars to analyze the reaction three different ways — the real substances, the chemical equation, and the molecular models. Class...

Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

Some chemical reactions produce heat, but what is really going on? Lesson focuses on the concept of energy changes, both exothermic and endothermic. Scholars perform multiple experiments, hands-on activities, and view videos of the...

Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...

How can you effectively provide detailed concepts of water properties to your high school class in a way they find exciting and challenging at the same time? By letting them play, of course! Through a variety of...

Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

Young chemists have unknown compounds they need to sort. Performing three different tests on each, the chemical behaviors they observe become the basis for data analysis. 

When a candle burns down, what happens to the mass that appears to be shrinking? Lesson begins with a demonstration of the chemical reaction of a candle burning. Then scholars use atom models to observe conservation of mass...

The radical reactions of polymers seems abstract to many pupils, but this lesson turns them into a fun building game. Scholars use dice and building pieces to build polymers. Then, they determine the theoretical and experimental weight...

You're bound to get a reaction from your classes with this experiment! Scholars perform several chemical reactions, make observations, and classify the reactions as single replacement, double replacement, composition, or decomposition...

How quickly do enzymatic reactions occur? Assist the class as they examine heat and pH change to determine the rate of chemical reactions using catalase as an enzyme. Watch them "glow" with excitement!

Junior chemists manufacture biodiesel in the lab. In this exercise, they check the purity of the biodiesel using thin layer chromatography. They also calculate its density and heat of combustion. They are sure to rise to the...

A chemistry lesson presents 14 chemical reactions for scholars to observe, write the equation, and balance the equations. Additionally, it provides ways to extend the activity as it relates to catalysts.

If your pupils think a catalyst is a list of their cats, then this might be the lesson for you! Young chemists study the effect of temperature, catalysts, concentration, and particle size on reaction rates during four different...

Using simple materials, an informative lesson demonstrates the Law of Conservation of Matter and explains how to balance chemical equations. Young chemists perform experiments, analyze reactions, and balance chemical equations...

Students explore chemical cahnges and the effect of temperature on chemical mixturees, They make observations of the behavior and appearance of certain chemical mixtures and reactions.

Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for...

Students study how to write chemical fomulas by reviewing the combinations atoms form into compounds. They write a procedure to test various substances and name the compounds and write formulas. As they construct models for formulas and...

High schoolers work together to observe the bond lengths of single, double and triple bonds. They make their own predictions about the strength of the bonds and chemical reactions. They answer discussion questions to complete the lesson.

Students are able to discuss the difference between a proton, a neutron and an electron. They also can explain the difference between an ionic and a covalent bond. Students know the main structure of atoms and molecules. Student are able...

Learners identify substances and discover common substances and their chemical composition.  In this chemistry instructional activity students write a description of the substances and how they are used.

In this reactions worksheet, students state the differences between a coefficient and subscript and an exothermic and endothermic reaction. Students review the different types of reactions. This worksheet has 13 short answer questions.
